We are happy to announce the release of Camunda Modeler version 1.12.0-alpha-1. This release marks the first ever alpha release of the Camunda Modeler. It features a completely rewritten DMN modeling that is blazingly fast and handles big decision tables with ease.

Blazingly fast DMN modeling

The new DMN modeling experience

If you’ve ever worked with a big DMN decision table using the Camunda Modeler you might have noticed that it becomes significantly slower as soon as you have a few hundred rules. In order to improve the performance of DMN modeling, we started to rewrite it from scratch. The result is a new modeling experience that is equally enjoyable with both small and big DMN decision tables. Speaking of performance:

Import time of a decision table with 500 rules in ms

Using the new DMN modeling you might notice that there are a few things missing. That’s why this is an alpha release.

Things you can do already:

edit decision name and ID

edit hit policy

add/remove rules/inputs/outputs

cut/paste rules/inputs/outputs

edit input expression/output name

edit input/output types

edit input/output entries

Things you can’t do yet:

drag/drop rules/inputs/outputs

copy rules/inputs/outputs

clear rules

edit input/output values

edit input/output entries using a simple mode

edit input/output entry expression language

add input/output entry descriptions

If you prefer performance over features the new DMN modeling you can already give the new DMN modeling a shot. If you want to use any of the features we haven’t rewritten yet please bear with us, we’re working on it.

Other Improvements

Besides a rewritten DMN modeling this alpha release also ships with new XML parsing that is significantly faster and fixes a few bugs that in the past allowed you to open invalid BPMN, CMMN or DMN.
